Specification of Letters rataaf To all whorn it mayconcemt: a

Be it known that I, LOUIE T.- Lewis, a

of Fletcher, in the county of, Comanche and State "ofOklahoma, have invented an Im proved Reinforced-Concrete Railway-Tie, of which the following is a specification.

My invention is a compositerailway. tie

formed of cement or'concret'e and ,a reinforce consistingof a skeleton metal frame. The latter is of peculiar construction, it

are so constructed and. "connected that .the

frame combines maximum strength, rigid'-' ity, and lightness.

Intheaccompanying drawing, Figure 1 complete tie. Fig.- 2 is a'plan view of the top plateforming part of the reinforcing frame. Fig. 3 is a perspective view of the reinforcing frame. The steel, skeleton, reinforcing frame is formed of three oblongrecta'n'gular plates,

to wit, top and bottom plates 1 and 2, which are spaced. apart vertically, and an inter. posed brace or truss-3, all ofwhich are provided with longitudinal central slots 4 and other shorter slots 51' located near the ends f e The top plate 1 is flat and the bottom plate 2 'is also flat save its-end portions,'

which'are bent twice at a right angle, thus forming terminal flanges 6 that serve as shoulders supporting the top plate 1. The

brace 3 is arched at the middle, orformed with an obtuse angle,whose central portion is riveted at7; to the, topplate 1, while-its flat depressed or bottom portions -8 are 1 riveted to the bottom plate 2, and its end portions, which j To form the complete tie, skeleton frame is embeddedin, or completely of about are riveted at 10 to and between the ends of the top and bottom plates .1 and-2. Thus the brace. 3-is rigidly'connected with and tiestogether the top and bottom plates and forms part of a rigid structure having maximum strength, rigidit lightness and durability.

covered by, cement or concrete, as shown in Fig. 1. In 'applying'the concrete, it. enters and lies in tl ese'vera'l slots-4 and 5 of the frame parts 1,2, and 3, and thus takes a firm hold'on"the frame.' The 's'lots furtherserve" to reducethe weight of the frame as well asits cost .of manufacture. The rails :22 are. secured .on the concrete body of the tie by means of bolts 11 which are mainly e mj bedded inthe concrete and passed through the plates 1, 2 and 3 at the suitable holes are provided, the upper ends of the bolts projecting above the body of the tie and the nuts applied thereto impinging on the rail base. The rails may be thus easilyand quickly secured on' the.-tie or released therefrom conditions require. What I claim is 1. The improved railwaytie, comprising frame which is embedded in the cement, the same being formed of slotted rectangular top and bottom plates, the latter having ends bent upward at a' right angle, and an inter;

posed brace consisting of a plate having a points 12 where a cement body' and a reinforcing metal raised obtuse-angled central portion, and

angular depressions near the'endswhich are secured between the top and bottom plates,

all the plates being riveted together at their several pointsof contact and the top and bottom plates being provided With coincifdent holes for reception of rail bolts, substantially as described.

- 2. The improved reinforce for cement ties, consisting of a skeleton frame formed of top and bottom plates and an interposed plate serving as a truss and brace, the central portion of-the latter being arched and riveted to the top plate and its end portions depressedand riveted to the bottom plate, its terminalsbeing secured between the ends of the top plate and the bottom plate, as shown and described.-
